Convert Femtosieverts to Millirems
Convert Femtosieverts (fSv) to Millirems (mrem) instantly and accurately.
Conversion Formula
mrem = fSv × 1.000000000e-10
About Femtosieverts
The femtosievert (fSv) equals 10⁻¹⁵ Sv. Used in computational nanodosimetry and Monte Carlo particle-transport simulations to characterise the equivalent dose from a single ion traversal through a DNA segment or cell organelle. Ultra-sensitive detector calibration in deep underground laboratories approaches the fSv level. 1 fSv = 10⁻¹⁵ Sv = 10⁻³ pSv.
About Millirems
The millirem (mrem) equals 10⁻³ rem = 10⁻⁵ Sv. Standard unit in US radiation protection: NRC occupational whole-body limit 5000 mrem/year; US average annual background ~300 mrem; EPA drinking-water dose limit 4 mrem/year; dose rates near US nuclear plant boundaries are reported in mrem/year. 1 mrem = 10⁻⁵ Sv = 10 µSv.
